About this code
Code P0444 registers when the powertrain control module detects an open circuit when commanding the purge valve. Often after maintenance like spark plug changes, the mechanic forgets to re-plug the solenoid. Drivability is unchanged and usually safe to drive for a short time, but get it checked.
